MCQ
A couple produces:
- ANo motion.
- BLinear and rotational motion.
- CPurely rotational motion.
- DPurely linear motion.
✓
Answer
- Purely rotational motion.
Explanation:
Hint: The forces that cause something to turn in a circle is called a couple.
A couple is nothing but two equal and opposite forces acting on a body having some separation between their line of action, as shown.
As the net force acting on the rod is zero so there will be no translational motion.
Net torque about O will not be zero as both forces are rotating the rod in the clockwise direction.

A projectile is thrown from a point $O$ on the ground at an angle $45^{\circ}$ from the vertical and with a speed $5 \sqrt{2} m / s$. The projectile at the highest point of its trajectory splits into two equal parts. One part falls vertically down to the ground, $0.5 s$ after the splitting. The other part, $t$ seconds after the splitting, falls to the ground at a distance $x$ meters from the point $O$. The acceleration due to gravity $g =10 m / s ^2$.
→($1$) The value of $t$ is. . . . . .
($2$) The value of $x$ is. . . . .

Two rings of radii 1 meter and 5 meter start rolling simultaneously on an inclined plane without slipping. Which ring will reach the earth's surface first?
Three identical particle $A , B$ and $C$ of mass $100\, kg$ each are placed in a straight line with $AB = BC =13 \,m$. The gravitational force on a fourth particle $P$ of the same mass is $F$, when placed at a distance $13 \,m$ from the particle $B$ on the perpendicular bisector of the line $AC$. The value of $F$ will be approximately$....G$
→If the velocity $v$ of a particle moving along a straight line decreases linearly with its displacement $s$ from $20\,ms ^{-1}$ to a value approaching zero at $s=30\,m$, then acceleration of the particle at $s=15\,m$ is $........$
